FIREARM.

' Application filed May 14, 1924. Serial No. 713,244.

' of which the following is a specification.

My invention relates to improvements in fire arms, and more especlally in shot guns, and its ob ects are: first, to provide a means whereby an ordinary shot gun may be readily converted into a magazine gun; second, to provide a means whereby a new cartridge will be' transferred to the gun barrel when the stock is broken down, and, third, to provide a means whereby the expulsion of a discharged cartridge from the gun barrel will trip a catch and allow the transfer magazine of my appliance to transfer a cartridge to, and into the gun barrel.

I attain these ob'ects by the mechanism and arrangement 0 parts shown in the-accompanying drawing, in which Fig. l is a right hand elevation of my attachment to the gun. Fig. 2 is a plan of a part of. a gun barrel and stock with my attachment in place. Fig. 3 is a like view with the stock shown as broken down and the transfer'magazine thrown over into position to discharge a cartridge into the breech of the gun barrel. Fig. 4 is a sectional elevation of my magazines on the line 44'of Fig. 2. Fig. 5 is a left hand elevation of my magazines detached from-the gun; Fig. 6 is a right hand side elevation of a gun with the stock, shown in outline as broken down. Fig. 7 is an elevation of the breech of the gun barrel with the cartridge eX- tractor case shown partly in section.

Similar reference numerals indicate similar parts throughout the several views.

My invention consists of a storage magazine 3 that is securely connected with the gun barrel 1, as with the pivotal bolt 14: and with a screw inserted at 15, so it will be made to remain stationary upon the barrel 1 when the gun stock 2 is being broken down, as indicated by its dotted outlines .in Fig. 6. Back of this magazine I mount a receiv ng and transfer magazine 4-, having a downwardly extending wing 4 which is pivotally connected with the downwardly extending wing of the magazine 3, shown at 3' by means of the su porting rod 5, which is securely connecte with the wing 3' at 5', and pivotally connected. with the win 4' so that the magazine 4 may he rea ily swung from its normal position back of the magazine 3, into position hack of the gun barrel'l, as indicated in Fig. 3. To bring about this action of the magazine 4 I place a strong spring 6 upon the supporting rod;5 and so connect said spring with said rod and with the wing 4' that when the gun stock 2 is broken down. as shown in Fig. 3 and indicated in outline in Fig. 6, the magazine 4 will be, thereby swung into position immediately back of the barrel breech, as in 3. 9 represents a set screw so mounted in the wing 4' that its inner end may be made to bearagainst the side of the gun stock and prevent the magazine from swinging too far over..

For the proper transfer ,of cartridges from the magazine 3 into the magazine I place a strong spring 11 in the magazine 3 in position to force the cartridge 13 backwardly into the magazine 4 as soon as the latter magazine is returned empty back of the magazine 3, and in the magazine 4 I place a much lighter spring, 12, that is light enough to allow the cartridges to he forced into the magazine 4 against it, and

still strong enough to force the cartridges from the magazine 4 into the gun barrel. when in position for this action. At 10 l have shown a guard that is made integral with the front end of the magazine -l to prevent the cartridges from being forced out of the magazine 3 when the magazine 4 is in position back of thc gun barrel. as in Fig. 3. It will be readily understood, referring to Figs. 2 and 3, that. al'tcr the gun stock has been broken down for discharging an empty cartridge and reloading the gun, the swinging of the stock hack into normal position, will easily morev the magazine 4 from the position shown in Fig. 3 back into the position shown in Fig. 2, preparedto receive another cartridge from the magazine 3.

If the magazine was left solely dependent upon its bearing upon the side of the gunstock for its support, as soon as the gun stock was broken down the magazine would follow and obstruct the way so the discharged cartridge shell could not be extracted from the gun barrel. To obviate this difficulty I place a' latch 7 upon the ,wing 4 in position to be made to engage a catch upon the wing-3. This latch is actuated by the spring 8 to throw it. into locking position, and has an upwardly and outwardly extending handle 7' thereon in position so that when a cartridge shell is forced out of the gun barrel by the shell extractor 17 the force of the shell striking the handle 7' will force the catch 7 longitudinally against the tension of its spring 8 and free the latch from the wing 3 and allow the magazine 4 to be moved into position back of the gun barrel. as hereintofore suggested. For proper action in this direction the spring 18 must be of sufficient tensile strength to throw the shell back with sufficient force. to absolutely operate the latch 7 as soon as the extractor bar 20 is freed from the lever or catch 19, all of which go to make up the. ordinary extractor mechanism of this class of guns. That these parts may be readily understood I have shown the extractor case 16 partly in section in Fig. 7.

14' represents the holes through the wing 3 of the magazine 3 through which the bolt 14 is to be passed to secure themagazinc to the side of the gun barrel.

At 21 I have shown a form of stop that may be used, if desired, to prevent the spring caps 22 from passing out of the magazines when the cartridges are forced out, but do not, of course, restrict myself to this particular form, nor do I desire to restrict myself, absolutely, to the exact construction of parts herein described and shown, as it is evident that other constructions may be readily made available for the purposes set forth.

Having thus fully described my invention, what I claim as new in the art, is:

1. In an attachment for break down guns, a storage magazine attached to one side of a gun barrel and stock, a spring therein for forcing cartridges out of the back endof the magazine, a transfer magazine pivotally mounted at the back end of the storage magazine and adapted to be made to swing over from the back of the storage magazine into position back of the gun barrel, and back again into position back of the storage magazine by the action of throwing the gun stock into breakdown position and again returning the stock into normal position.

2. In combination with the elements covered in claim 1, a pivotal rod and spring for throwing the transfer magazine from normal position into position back of the gun barrel when the gun stock is broken down.

rel, and a trip for releasing said catch whenv the gun stock is'thrown into breakdown position.

4. In combination with the elements covered in claim 1, a spring mounted in the transfer magazine of a proper tension to allow a cartridge to be forced into this mag azine by a stronger spring in the storage magazine, and to force a cartridge from this magazine into the gun barrel.

5. Incombination with the elements covered in claim 1, a guard extending outwardly from one side of the front end of the transfer magazine to prevent cartridges from passing out of the storage magazine when the transfer magazine is in position for discharging a cartridge into the gun barrel.

6. In combination with the elements covered in claim 1, a rod secured to the storage magazine and pivotallysupportmg the transfer magazine, a spring connected with said rod and with the transfer magazine for carrying the transfer ma azine over into position directly back of t e gun barrel, a catch for holding the transfer magazine in normal position, a trip for releasing said catch when the gun stock is broken down, a guard upon the front end of the transfer-magazine for preventing cartridges from passing out of the storage magazine when the transfer magazine is depositlng a cartridge into the gun barrel, and a gage screw for gaging the position of the transfer magazine when it is in position back of the gun barrel.

7. In combination with the elements covered in claim 1, a catch for holding the transfer magazine in normal position until the discharged cartridge is expelled from the gun barrel, and means whereby the discharge of said cartridge will trip said catch and allow the transfer magazine to be carried into position to discharge a cartridge into the gun barrel.
